The acquisitive Chinese group has disclosed more than ever about its owners, but that won’t stop the questions

Scrutinizing the ownership of HNA Group always brings to mind Winston Churchill’s well-worn description of Russia as a riddle wrapped in a mystery inside an enigma.

The acquisitive Chinese company, which owns a nearly 10% stake in Deutsche Bank and is trying to buy White House communications director Anthony Scaramucci’s SkyBridge Capital, says it is trying to be more transparent. On Monday it disclosed new details about its shareholders, listing 15 individuals and entities it says are its ultimate owners.
